Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/xe/pf: Don't attempt to process FAST_REQ or EVENT relays
Currently defined VF/PF relay actions use regular REQUEST messages
only and the PF shouldn't attempt to handle FAST_REQUEST nor EVENT
messages as this would result in breaking the VFPF ABI protocol
and also might trigger an assert on the PF side.
(cherry picked from commit 1714d360fc5ae2e0886a69e979095d9c7ff3568a)
A flaw was found in the Linux kernel's drm/xe/pf component. The Physical Function (PF) incorrectly attempts to process FAST_REQUEST or EVENT messages, which are not part of the defined Virtual Function to Physical Function (VFPF) Application Binary Interface (ABI) protocol. This misprocessing can lead to a violation of the VFPF ABI protocol and may trigger an assert on the PF side, potentially resulting in a denial of service.
